CYS Audio/Video Downloader
Free Downloader for Firefox, Sea Monkey, and Pale Moon
Update January 2024: CYS has been disabled on the AMO site as legacy add-ons
are no longer compatible with current versions of Firefox. CYS has not been abandoned. We are rewriting
the code from scratch, for all three browsers. We will be back soon with a new and improved version. Continue
to CYS website here.
We are not responding to tech support emails at this time.
